This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X90SFA, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SU63-100 Standard Cylinder SU80X90SFA
The AirTAC Airtac SU63-100 Standard Cylinder SU80X90SFA is a double-acting profile-type standard cylinder with a Ø80mm bore and 90mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X90SFA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X90SFA
The AirTAC SU80X90SFA is a discontinued double-acting profile-type cylinder with an 80mm bore and 90mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, scaling to 3518N at 0.7MPa. The direct replacement is the SAU80X90SFA, matching the 3/8" port, M20x1.5 rod, and SC-series FA mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. The SAU upgrade switches the -S magnet to CMSG/DMSG/EMSG sensors and adds the SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X90SFA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X90SFA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SU63-100 Standard Cylinder SU80X90SFA Is Used
Press Fit Assembly
Drives 128kg vertical loads to seat bearings, leveraging the 1508N safe working output and 90mm stroke for precise pressing.
Heavy Package Divert
Uses the FA foot mount to securely push heavy pallets or totes off a transfer line, utilizing the 2513N push force at 0.5MPa.
Pallet Stop Gate
Acts as a robust 80mm bore stopper in material handling zones, with the compact profile saving space in tight conveyor frames.
Replacing the Airtac SU63-100 Standard Cylinder SU80X90SFA with the SAU80X90SFA
To replace this SU80X90SFA, order the SAU80X90SFA keeping the 80mm bore, 90mm stroke, 3/8" port, and FA foot mount. If downsizing, the 63mm bore yields 1559N push at 0.5MPa; if upsizing, the 100mm bore gives 3927N. The -S magnet on this legacy SU used CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for held loads. The SAUF valve-integrated variant is a new option if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU80X90SFA
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU63-100 Standard Cylinder SU80X90SFA FAQ
Yes, the SU80X90SFA is discontinued. The direct replacement is the SAU80X90SFA, offering the same 80mm bore, 90mm stroke, 2513N force, 3/8" port, and SC-series FA mounting compatibility.
It pushes 2513N and pulls 2268N at 0.5MPa, pushes 3518N at 0.7MPa, and reaches a max of 513kgf at 1.0MPa. The -S magnet on this SU worked with CS1-B/DS1-B switches; the SAU replacement uses CMSG/DMSG/EMSG sensors.
